Description

[Detailed description of the invention] The purpose of this invention is to facilitate the installation and removal of accessories such as panels and frames for lighting equipment.

An example of this invention will be explained with the help of diagrams: 1
1 is the main body of the device, in which a ballast and other lighting appliances are housed, and is fixed to the structure with a suspension bolt (not shown). Reference numeral 2 denotes a reflector mounting frame, which is attached to the instrument main body 1, and 3 a reflector plate, which is detachably fixed to the reflector plate mounting frame 2 with screws 4. 5 is a fluorescent lamp, and 6 is a ceiling.

The above configuration is well known as, for example, an open-type ceiling-embedded lighting fixture, which is traded as a single product or used by being installed on a ceiling or the like. However, lighting fixtures with such a configuration may be required to be used as so-called closed-type fixtures, in which the lower surface is closed with a translucent panel, or as so-called light-shielding fixtures, in which a butt-full is installed. All you have to do is set up Batsuful etc. Even when such panels are installed, the upright wall at the side edge of the reflector 3 is required to be in contact with the ceiling.

Therefore, in this invention, in order to facilitate the installation of such accessories, for example, panel 8 is installed as shown in the figure.
A frame 9 for supporting the frame 9 and its surroundings is prepared, and a mounting fitting 10 is also prepared. The panel 8 is supported at the lower edge of the frame 9 by a presser metal fitting 11, etc., and by installing this frame 9 on a lighting fixture,
The lower surface can be closed using the panel 8. The same applies when using Batsuful.

As shown in FIG. 2, the mounting bracket 10 has a flat center wall 12 with a downwardly directed tongue piece 13, and a U-shaped hook 14 on one side edge of the center wall 12. There is. Note that a bent portion 15 is provided on the other side edge as necessary. The mounting bracket 10 includes a tongue piece 1
3 and one side wall 14A of the hook portion 14,
The reflector plate 3 is attached by inserting a standing wall 3A in which the outer peripheral edge of the reflector plate 3 is raised. If the lighting fixture is already installed, loosen the screws 4, lower the reflector 3 a little, create a gap between the upright wall 3A and the ceiling 6, and insert the mounting bracket 10 through this gap. Just do it.

To attach the panel 8, and therefore the frame 9, to a lighting fixture using the mounting brackets 10, first lower the reflector 3 a little as shown in FIG. Insert it into the gap between the back side of the At this time, the mounting bracket 10 is tilted so that the bent portion 15 inside thereof comes into contact with the ceiling 6. In this state, the upper edge 9A of the frame 9 (which is bent into a key shape, for example) is hooked onto the hook portion 14. At this time, weight is applied to the hook portion 14 and it attempts to descend, but the engagement between the tongue piece 13 and the upright wall 3A prevents the descent. Also, using this engagement point as a fulcrum,
The mounting bracket 10 tries to rotate due to the weight on the hook 14, but the rotation is restricted because the inner end of the mounting bracket 10 (the bent part 15 in the figure) is in contact with the ceiling 6. be done.

In this state, the reflection plate 3 is then pushed up. Then, as shown in FIG. 4, the mounting bracket 10 rotates in the direction in which the hook portion 14 rises, using the contact point between its inner end and the ceiling 6 as a fulcrum. During this rotation process, the upright wall 3A and the tongue piece 13 are still engaged, so the mounting bracket 10 will not fall off. When the reflector 3 is pushed up sufficiently, the center wall 12 of the mounting bracket 10 will be sandwiched between the upright wall 3A and the ceiling 6, as shown in FIG. is sandwiched between the outer side wall 14B of the hook portion 14 and the ceiling 6. In this position, the reflector 3 is sufficiently fixed to the reflector mounting frame 2 by screws 4. Note that the above-mentioned pushing up of the reflecting plate 3 may be done by tightening the screws 4.

The frame 9 installed as described above is installed so as to be sandwiched between the mounting bracket 10 and the ceiling 6, and the engagement of the tongue piece 13 with the upright wall 3A prevents the mounting bracket 10 from being removed. Since it is prevented,
The frame 9 is reliably prevented from coming off the reflecting plate 3. This installation is extremely easy because it is only necessary to engage the mounting bracket 10 with the reflecting plate 3, the frame 9 with the mounting bracket 10, and push up the reflecting plate 3. Furthermore, the mounting bracket 10 can be easily attached to an existing lighting fixture. Therefore, it is effective when adding accessories such as panels to existing lighting equipment.

As detailed above, according to this invention, it is extremely easy to attach and remove accessories such as panels and brackets, and it is also possible to easily attach and remove these accessories from existing lighting equipment. Moreover, even after the accessory is installed, the upright wall of the side wall of the reflector can be brought into contact with the ceiling in the same way as before the attachment.

Claims (1)

[Scope of utility model registration request] A ceiling-embedded device body, a reflector mounting frame attached to the device body, and a reflector mounting frame fixed to the reflector mounting frame with screws. a reflector whose tip faces the ceiling; a tongue piece on a flat central wall; and a U-shaped hook connected to one side edge of the central wall; By inserting the upright wall of the side edge of the reflector so as to be sandwiched between the tongue piece and the center wall while the other side edge of the reflector is in contact with the ceiling, It consists of a mounting bracket that is engaged between the upright wall of the reflector and the ceiling, and a frame for an accessory such as a panel or buttful whose upper edge is hooked on the hook of the mounting bracket, and the hook is connected to the hook. In the hooked state with the frame, as the reflector rises by tightening the screws, the mounting bracket rotates until the upper end of the frame comes into contact with the ceiling. A lighting fixture whose rotational fulcrum is the other side edge of the central wall of the mounting bracket that is in contact with it.
